, siding at Dayton, county of Montgomery, State of Ohio,. have. 'invented certain new and useful Improvements in` Pumping AP* params, of which the following. is" a ful1,.

clear, and-exactdescription. f 1

The present invent1on'relates -to pumping apparatus wherein the pump is located vvith-l i operatmg mechanism above in a well and the and to provide for the removal of certain pump parts in assembled relation from the I i. well casing by devices whichare easily accessible from above the well. l

More particularly, the present'invention contemplates the use of a suction-lift pumpv for a well in which thedistance 'from the low level ofthe water there-in to the level of the pump outlet, is somewhat' in excess of.

the distance which it 'is practical to lift water by suction, namely, in excess 01E` twenty-two feet which is the limit of liftcharacteristics of most suction ty ypumps. The present invention permits t 'e use'cf asuction pump in such a well to' draw the water themaximum distance by '.suction, and then force or lift the water theremaining distance to thel discharge level'.

One manner of carrying out these -aims of the invention is to locate within the well andy below the frost line a support connected to the well casing and having a vdischarge port connected with an outlet pipe located so as to be outl of danger of freezing. This part of the a aratus can be permanently installed. he drop pipe enclosing the suction-lift pump isregnovably mounted upon i the support and has an outlet tothe dis'- use of the devicesaccessible from above theA charge port of its support. The pump parts and drop pipe are removed as a unit from the well casing and -irom thesupport by the well.

g Further objects .and 'advantages of thel 1 present invention willbe apparent from the following description, reference being had to the accompanying drawings, wherein a 'preferred embodiment of one form of the present invention is clearly shown.

Ip the drawin s, a base 20 may support a suitable pump riving mechanism such as .sh )wn in the copending apgnlicaton'of G. A.

Buvin erand (J. Warner, erial No. 634,323, filed l arch 12, 1923. Base 20 is placed directl over a well casing 'having an upper .portion 2l anda lowerportion 22 which are .coupled together by a discharge head 23.

Discharge head 23 is connected to discharge pipe 24 which may lead to a suitable storage tank located in a basement or other location out of the weather. Casing 21-.i.s..ofsuch length that the discharge head 23 and the discharge pe 24 are buried in the ground below the rost line.

After the well casing 22 has been driven a small pit isdug around the casing to adepth on. l

below the frost line. `The casing, 22 is cut v 0H below the frost line and the discharge head 23 is placed on top of casing l22 and secured thereto by screw 25. The upper casing 21 is laced in vertical position with its lower end) received by the head 23 and is secured thereto by screw 26. After pipes 25 and 22 are attached, the pit is filled with cement 27 so as to provide a seal for theV well casing which extends above ground and is protected in a mannerto be described.

- Discharge head 23. is provided. with a seat -30 which is tapered about live degrees and is less in diameter than the internal diameter of casing21. The seat 30 is bypassed by a passage 31 which is provided for a purpose to be described. 'llie seat 30 provides a support for devices 'which support the pump cylinder or' drop pipe and provide packing for a differential piston operating within said drop pipe, the seat 30 cooperating with rest upon the seat 30. The hanger 32V is pro-l I to provide a water passage into the dis these devices to provide a seal preventing water issuingfrom the pump. above the frost line.

,One of these sealing and supporting devices comprises a hanger 32 provided with a comcal outer surface adapting the hanger to vided with a groove 33 and an opening 34 charge head 23. Hanger 32 supports a pump cylinder comprising sections 35 and 36 joined by a coupling 37. Thesection 36 extends to within substantially twenty two .'feet or less of the lowest level which the valve body `42 limits Vupward movement of `ball 43.

' A pump rod having upper and lower sections and 51v respectively are connected by a coupling 53 which supports a differential piston 52. A piston 54 having ports 55, y`516, and 57 is secured to the lower end of section 51 of the pump rod, and is provided with a valve 58 for controlling port 57. Piston 54 is adapted to be reciprocated within the cylinder section 36 and differential piston 52 is adapted to be reciprocated within section 35 and the hanger 32 by the pump driving mechanism referred to.

Another device which cooperates to provide packing between the 4hanger 32 and the differentiall piston 52 is a stuling box 59 which hasv threadedy connection with the hanger 32. Hanger 32 has threaded con` nection with an extension pipe 60, extending above the upper end of well casing 21.

The pump base 20 is provided with a downwardly extending flange 61 into which ,the casing 21 extends. By permitting the casing' 21 to slide 'within the flange 61, expansion or contraction of the casing 21 lon` gitudinally can take place without raising or lowering.the base 20. Base 20 is provided' with an opening 62 into which a.l pulling flange 63 may extend. Pulling Hangs 63 is connected with Hanged ortion 64 aving threaded connection wit extension i e 60 above the upper end of casing 21. u ing flange 63 can move vertically through the opening 62 whereby expansin or contraction of the kipe 60 may take place With-V out affecting t e pump base 20. Tapped holes 65 are provided in -the flange 63 through which bolts 66, having al diameter less than the diameter of the tapped holes 65, are adapted to extend and to screw into the pumpbase 20. lSprings 67 are interposed between the heads of these bolts 6 5 and the flange 63v and tendto maintain the-hanger 32 upon its seat 30. In this manner the hanger 32 is held in nested relation with respect toI the discharge head 23 by means which can yield in response to ldifferences-in expansion or contraction of parts ofthe ap'- paratus. Thus the discharge `head will be maintained sealed for all temperatures and without danger of breakage of parts.

v vMode of operation.-

Fig. 1 shows the pumping apparatus just/rv starting on an upward stroke. As the piston 54 moves upwardly within section or cylinder 36, the suction created thereby will open valve 39 and foot valve 43, whereupon water will be drawn from the well through strainer .45, passage 44, valve body. 42, pipe 41, passage 40,'into the cylinder36. As explained before, the distance from the valve 43 to the valve 39 must not be greater than approximately twenty, two feet, this distance being the, maximum distance which it l is practical to draw Water l,by suction. Then on the downward stroke of piston 54, the valve 39 will be closed and the valve 58 opened, thereby permitting water to flow from cylinder 36, through .passage 57, ports 55 and 56 into the section 35. 'The water 'will then come into contact with differential ill) piston 52, which is ofsuch diameter as to v displace substantially one half of the water lifted on the up-stroke into section 35." Thuis piston 52 being on its downward travel will ,therefore force about one half ofthe waterl lifted into section 35 into hanger 32, through discharge opening 34 therein into the discharge pipe 24. On the next upward stroke of plston 54, water will be drawn into the cylmder 36 as before described, and the water remaining in section 35 will be lifted upwardly by piston 54 to .the hanger 32,

into scharge pipe 24. This cycle of operation will continue as long as the pumping apparatus is operated.' Namely, the water will be drawn by suction from the well up to the level of the valve 39, and upon the down stroke of piston 54 and differential pis ton ,52, about one half of the water previously lifted into section 35 will be forcedout into discharge pipe 24, and on the upward stroke of piston 54,l the water remaining in section 35 and section 36 above ton 54 will be lifted up and out through throuigh discharge opening 34 therein and' gisis- 'y charge pipe 24. Thus for each stroke of the pump rod in either direction, there will I be a discharge of water through pipe '24. It will be apparent that the drop plpe, comprising sections 35 and 3 6, constitutes a level of opening (0, at which time the Water Iwill flow through opening 70 into pipe 21,

through passage 31, pipe 22 and to thel well,

, to prevent water building up further in pipe 67 and thereby prevent flooding of the pump -drivingmechai'sn or freezing. of water therein.

v68 to be engaged by bolts 66. To'remove the pumping. apparatus, the drivingmecha nisin is uncou led from the pump rod sec-- tion 50 and' ange 63, land shiitedtoA one side of basev20, and the bolts 66 are with' drawn from the base 20 as shown in Fig. 4, and are screwed into the holes 68 of the flange 63. When 'these bolts 66 are shifted so as to be screwed into the holes 68, they are thrown out of alinement with the holes in theb'ase 20 as shown in Fig. 5, and then by screwing the bolts 66 downwardly they will bear against the p'ump base 20 as shown in Fig. 2. Further Vmovements of vthese bolts 66 will cause thepulling ange 63 to move upwardly thereby lifting hanger 32 from its seat 30 and permitting the pumping apparatus `to.be removed from the well casing in assembled relation, as, above described. Fig. 4 shows the location of the bolts 66.when the mechanism is in normal operation while Fig. 5 shows the bolts i-n the position in. which they are used for lifting the pulling flange 63. The tappedv holes 65 are provided for receiving screw eyes V(not shown) which may be attached to a hoist for lifting the pumping apparatus out of the well casing.

' It is obvious that the pumping-apparatus may be installed as a un1t by merely insert# ing it into the well casing, and when' lowered therein= the hanger 32 will be automatically will remain in the'springs to maintain a Y downward pressure upon the extension` pipe 60 to maintain the hanger 32 upon its seat i 30. Any freezing of the earth above the discharge head 23 will cause the base 20 to `be moved upwardly away from the casing 21 and the extension pipe 60. This Amovement is possible since the casing 21 is' yfree v from positive connection with thebase 20, and as the base 20 moves upwardly carrying the bolts 66, the tension in springs 67 wil decrease.'

Fig. 6 shows an installation when the power head'base 20 is located in an exposed place'on theground over an open well 100. The discharge head 23 is vsuspended from the base 20 at a distance such as to be outiof danger from frost by like flanges 101 a d 102 attached to an extension pipe 103, bol ts 104 attaching ange 101 to base 20, andppy bolts 105 attaching discharge head 23 to liange 102. 1
